metalmonkey47 Posted August 11, 2011 Report Share Posted August 11, 2011 Interesting. I unhooked the "T" signal wire from the alternator because it has a drain on it (traced the harness and still haven't found it) so it wouldn't roast my battery while I go in and eat, and started it up to move for a second and noticed with it unplugged, the alternator still charges at 14V via my gauge. I checked it at the battery and it's all correct. What would cause this? I've never seen a car charge with the signal unplugged. I also noticed the my idle is more stable, it has a more power, and just feels better from every standpoint. Quote Link to comment
ggzilla Posted August 11, 2011 Report Share Posted August 11, 2011 I have seen that before. An alternator can have an internal short in it and charge all the time. It may or may not drain the battery when the engine is not running. If you have both of the Tee wires disconnected, then it is getting the charge signal from A connected (battery) due to internal short. Quote Link to comment
